AI QA built for Node.js APIs

API endpoints are the attack surface of your application. VibeProof reads your route handlers and generates test cases for authentication, authorization, input validation, error handling, and data integrity — the categories where most production bugs live.

What VibeProof tests

Auth and authorization — missing middleware, workspace/tenant isolation, role checks, token validation
Input validation — type coercion, boundary values, injection payloads, missing required fields
SQL/ORM safety — parameterized queries, N+1 detection, transaction boundaries
Error handling — consistent error response format, no stack trace leakage, proper status codes
Rate limiting — endpoint-level limits, per-user throttling, abuse prevention
Response consistency — pagination limits, field filtering, null handling across endpoints

Why this matters

Node.js APIs are where data enters and leaves your system. Every endpoint without proper validation is an invitation for bad data. Every endpoint without auth is a data leak. VibeProof treats your API as an attack surface and generates test cases that a security-conscious QA engineer would write.

Example test cases

SQL injection via query parameter

1.Send GET /api/users?search='; DROP TABLE users; --

2.Check database state

3.Verify response

Expected: Query is parameterized. No SQL execution. Returns 400 or filtered results.

Cross-tenant data access

1.Authenticate as user in Workspace A

2.Request resource belonging to Workspace B via /api/resource/{workspaceBId}

3.Check response for data leakage

Expected: 403 Forbidden or 404 Not Found. No data from Workspace B exposed.

FAQ

Does VibeProof work with Express, Fastify, and Hono?+

Yes. VibeProof reads your route handlers regardless of the framework. It understands middleware patterns, route grouping, and plugin architectures across Node.js frameworks.

Can it detect SQL injection vulnerabilities?+

VibeProof generates test cases that specifically target injection points — string concatenation in queries, unparameterized inputs, and unsanitized user data in database operations.
